When did your car last have an oil and spark change ? If it's been awhile that might explain it.
Also it was quite hot yesterday which will have an affect.
spark plugs not been done since I've owned it about 4 months ago but might go about getting some now... NGK you guys recommend?
oil was replace twice this year. cracked sump nut seal caused a leak that just wouldn't go away and both times I had brand new VW spec Quantum put in. she runs very well and economically tbh.
think the heat just made her tired, lol
